Title: Device for the mains-supply operation of cathode ray tubes
IPC: H04N5/68
Filed: 1933-07-10
Abstract: 407,857. Television. RADIOAKT. - GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. July 10, 1933, No. 19454. Convention date, July 11, 1932. [Class 40 (iii).] Cathode-ray tubes are operated from the mains and special screening 12, 13, 15, 38 and filtering 43, 45, 6, 7, 17, 19, 18, 20 prevent ripple reaching the electrodes of the tube, particularly the cathode 4 and Wehnelt cylinder 2. The filters include high ohmic resistances 6, 17. The time constant of the main smoothing condenser 5 and the load is approximately one hundred times the period of the mains. The circuit of the control electrode is connected to the electric centre of the cathode, for example, a tapping on a potentiometer 8 or on the transformer 11 supplying the heating-current. The transformer 11 is separate from the high-tension transformer 10, and the secondary winding 9 with its leads and the filament rheostat 14 and other parts of the filament circuit are enclosed in a metallic screen 12, 13, 15. The heating-current is preferably regulated by a resistance 16 in the mains lead. A protective resistance 21 is connected directly to the anode 24 and is earthed on the side remote from the anode. The rectifying valve 34 has small capacity and preferably an earthed screening-grid 37, and the lead 39 is enclosed in a screen 38.

Abstract: Vinylmercuric esters or vinyl esters are prepared by reacting divinyl mercury with an organic carboxylic acid.  The carboxylic acid may be of formula Rq(COOH)p wherein p is 1 or 2, q is 1 when p is 1 and q is 0 or 1 when p is 2, and R is hydrogen or an alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, aralkyl or alkaryl radical and the divalent equivalents thereof when p is 2 which may be substituted by chlorine, bromine or iodine atoms or by hydroxyl groups.  Reaction at room temperature or above yields vinyl esters and may yield the intermediate vinylmercuric ester which may be isolated if desired. The vinylmercuric ester is converted to the vinyl ester on heating. Using a monocarboxylic acid, the reactions may be represented: RCOOH+(CH2=CH)2Hg --> RCOO-Hg-CH=CH2+CH2=CH2 RCOO-Hg-CH=CH2 --> RCOO-CH=CH2+Hg.  Using a dicarboxylic acid, the following products may be obtained:  HOOC-Rq-COO-Hg-CH=CH2 HOOC-Rq-COO-CH=CH2 CH2=CH-Hg-OOC-Rq-COO-Hg-CH=CH2 CH2=CH-OOC-Rq-COO-CH=CH2 CH2=CH-OOC-Rq-COO-Hg-CH=CH2  The reaction may be conducted in a solvent or diluent, and in these circumstances the production of the vinyl mercuric ester is favoured. Suitable solvents include aliphatic and aromatic hydrocarbons, lower aliphatic ethers, tetrahydrofuran, tetrahydrothiopene, dioxane, ethers of ethylene glycol and diethylene glycol and lower aliphatic alcohols.  Other conditions favouring production of the vinyl mercuric ester are short reaction time, low reaction temperature and stoichiometric quantities of reactants.  The production of the vinyl ester and the more complete reaction of all the carboxyl groups in the polycarboxylic acid are favoured by absence of solvent, higher reaction temperature, longer reaction time and an amount of divinyl mercury in excess of the stoichiometric quantity.  The invention also includes as new compounds the vinyl mercuric esters of monocarboxylic acids of formula R.COO-Hg-CH=CH2, and the vinyl mercuric ester derivatives of dicarboxylic acids of formulae HOOC-R-COO-Hg-CH=CH2, CH2=CH-Hg-OOC-R-COO-Hg-CH=CH2 and CH2=CH-OOC-R-COO-Hg-CH=CH2 where R is as defined above.ALSO:Oil paints contain as a fungicide a vinyl mercuric ester of a mono- or di-carboxylic acid.ALSO:Vinyl mercuric esters may be added to paper pulp prior to processing it into paper to prevent fungus attack.

Title: Improvements in and relating to the gasification of bituminous coal and the like
IPC: C10J3/00
Filed: 1923-08-02
Abstract: 216,021. Humphreys & Glasgow, Ltd., (Rusby, J. M.). Aug. 2, 1923. Producers; coking processes.-Bituminous coal is gasified by establishing two hot zones in a fuel bed, generating combustible gas in one zone, superheating the gas by passing it through the other zone, and passing the superheated gas through the coal in a carbonizing chamber which may be superposed on the hot fuel bed. Coal is fed into a carbonizing chamber 2 and the resulting coke fills a gasifying chamber 3 in which two hot zones b, d are maintained, the lower one by air admitted below the grate and the upper one either by air passed downwardly from ports 7 or by air supplied through secondary inlets 32 for burning the producer gas. During the run, steam is admitted below the grate and the water gas generated in the lower zone d is superheated in the upper zone b and passed through the fresh charge in the, chamber 2, the mixed water gas and coal gas being led either by a pipe 17 to a holder or by a branch pipe 31 to a main 12 leading to a carburettor which is preheated by the gases generated during the blow. Prior to the steaming, and if the fresh charge is wet or not easily carbonized, the hot gases in the generator 3 are circulated through the chamber 2 and pipe 17 and back by pipe 23 to the generator. The gases generated in the chamber 2 during the blow may be bypassed to the main gas outlet. A mixture of water gas, coal gas and producer gas may be obtained by passing the gases during the blow through the chamber 2, steam being added to the air blast, or producer gas and water gas may be alternately passed through the chamber 2.

Title: Improved method and apparatus for determining the calorific value of gases
IPC: G01N25/40
Filed: 1924-08-22
Abstract: 222,839. Dorgelo, J. I. Oct. 1, 1923, [Convention date]. Fluid-actuated valves.-A gas calorimeter is automatically operated in a succession of steps in each of which a constant volume of gas is burned. The gas enters by a pipe E and down a pipe F into a container B, excess gas being burned at the open upper end of the pipe F. Below the container B and communicating therewith is a tube Q the reduced lower end of which passes into a vessel A. Water is introduced into the vessel A from a pipe D down a tube J which surrounds a tube H open to the atmosphere at its upper end. When the water rises in the vessel A to the level of the lower end of the tube H the air in the vessel is trapped and its pressure rises as the water continues to enter, thus causing the water to rise in the tube Q until the lower end of the pipe F is covered. Gas is thereafter expelled from the container B through a pipe K to a burner M where it is ignited by a by-pass burner N. The water rises in the tube H until it siphons over down the tube C and enters a vessel U from which it passes into the calorimeter, displacing the heated water therein. At the same time the liquid seals are broken, and a fresh charge of gas enters the container B. To prevent entry of air to the container during the siphoning operation the tube K has a U-shaped part L within the vessel U, this part L having an open lower end so that as the water rises in the vessel U it forms a seal within the tube L.
